Network Diagram Practice

Base your analysis of the following three projects on the information in the table. Each project has been defined to contain a list of activities/tasks (each identified by letter) along with the immediate predecessor activities and the optimistic, most likely, and pessimistic time estimates (in days) for completion.

Project A:

1. Use the 3-point (PERT) method to calculate the normal duration for each task (round to the nearest whole number) and enter in table.
2. Construct a labeled network diagram (include duration, early/late times) on paper then insert the image below the table.
3. Calculate and enter the free slack and total slack for each task in the table.
4. List all paths with durations and identify the critical path.

Task	Predecessor	a	m	b	Normal duration	Free Slack	Total Slack
A	---	3	4	7
B	---	4	6	10
C	A, B	5	8	11
D	A	8	9	12
E	C	7	8	9

Project B:

1. Use the 3-point (PERT) method to calculate the normal duration for each task (round to the nearest whole number) and enter in table.
2. Construct a labeled network diagram (include duration, early/late times) on paper then insert the image below the table.
3. Calculate and enter the free slack and total slack for each task in the table.
4. List all paths with durations and identify the critical path.

Task	Predecessor	a	m	b	Normal duration	Free Slack	Total Slack
A	---	4	4	8
B	A	3	4	6
C	B	4	7	10
D	A	6	9	11
E	D	7	10	12
F	E	5	8	12
G	E	6	7	9
H	C	15	16	18

Project C:

1. Use the 3-point (PERT) method to calculate the normal duration for each task (round to the nearest whole number) and enter in table.
2. Construct a labeled network diagram (include duration, early/late times) on paper then insert the image below the table.
3. Calculate and enter the free slack and total slack for each task in the table.
4. List all paths with durations and identify the critical path.

Task	Predecessor	a	m	b	Normal duration	Free Slack	Total Slack
A	---	4	4	7
B	---	3	4	5
C	---	4	7	10
D	B, C	6	8	10
E	A	7	9	12
F	D, E	3	4	12
G	C	6	7	9
H	F, G	10	12	15
I	E	14	14	18
